Facial recognition technology needs controls on its use, World Economic Forum says

Governments need to take people's privacy into account as more and more countries consider using facial recognition technology to beef up security, said an expert at the World Economic Forum. Facial recognition software is powerful biometric technology that can identify individuals based on digital images or video frames. Artificial intelligence, high-definition surveillance cameras, and remote sensors have made the technology more powerful and expanded the ways it can be used. "The problem's really two-fold," Kay Firth-Butterfield, head of artificial intelligence at WEF, told CNBC at the India Economic Summit.
